Abstract
Description
Technical Field
[0001] This utility model relates to the field of label technology, specifically to a novel laser-engraved high-viscosity, weather-resistant label. Background Technology
[0002] In modern packaging, labels are an important material for information identification. They also serve multiple functions such as brand promotion, anti-counterfeiting, and functional protection, and are therefore widely used in various fields, including food packaging, daily chemical product packaging, and pharmaceutical packaging.
[0003] In particular, food packaging and daily chemical product packaging often involve products that need to be in contact with moisture for extended periods. For example, beer or other beverages are often cooled with ice water or refrigeration to improve their taste. After refrigeration, a large number of water droplets will condense on the product surface at room temperature, or direct contact with ice water will damage the adhesive on the product label, significantly reducing its adhesion and damaging the product's appearance. Alternatively, products that need to be in a humid environment, such as shower gel, shampoo, or skin care products, will experience moisture in the air gradually penetrating into the label when stored in a high-humidity environment for a long time. This will have an adverse effect on the label paper. In addition, frequent handling may cause the label surface coating to peel off or the pattern to become blurred.
[0004] To address these issues, label materials widely used in the market typically have a waterproof coating applied to the label surface to enhance their waterproof performance. However, the adhesion between this waterproof coating and the label paper is limited. When exposed to a large amount of water, the coating's adhesiveness decreases, and its poor abrasion resistance makes it susceptible to friction damage, thus reducing the label's lifespan.
[0005] Most labels are handwritten, and their effects are easily oxidized and deformed when exposed to air for a long time, which greatly affects the actual sensory effect of the labels. They are also prone to fading or wear, making it difficult for them to meet the needs of daily life and production. Utility Model Content
[0006] This invention addresses the shortcomings of existing technologies by providing a novel laser-engraved, high-adhesion, weather-resistant label. The label uses a polyester or polyimide film with excellent weather resistance and mechanical strength as its substrate. By bonding a printing layer and an adhesive layer to the substrate, laser engraving technology enables high-precision printing of patterns and text on the label surface. The printing effect is durable and clear, suitable for printing complex patterns and barcodes. High-performance acrylic resin adhesive gives the label high initial tack and holding power, allowing it to firmly adhere to various material surfaces and maintain stable adhesion under different environmental conditions. The use of a weather-resistant substrate and a UV-resistant coating enables the label to be used for extended periods in harsh outdoor environments, resisting UV rays, rain, high and low temperatures, maintaining the label's functionality and aesthetics. Laser engraving printing technology eliminates the need for ink, reducing environmental pollution and improving printing efficiency, making it suitable for large-scale production.
[0007] To achieve the objective of this utility model, the technical solution adopted is as follows:
[0008] A novel laser-engraved high-adhesion, weather-resistant label includes a label substrate layer in the middle, a laser-engraved printing layer on top of the label substrate layer, a label adhesive layer below the label substrate layer, and a label release paper layer below the label adhesive layer. Shielding aluminum foil layers are wrapped around both sides of the label substrate layer. A flame-retardant soft ceramic layer is disposed between the shielding aluminum foil layer and the laser-engraved printing layer, and a flame-retardant soft ceramic layer is also disposed between the shielding aluminum foil layer and the label adhesive layer.
[0009] As a preferred technical solution, the thickness of the label substrate layer is 0.075 mm, and the thickness of the label substrate layer is less than or equal to the thickness of the laser engraving and printing layer.
[0010] As a preferred technical solution, the thickness of the label adhesive layer is 0.03 mm, and the thickness of the label adhesive layer is greater than or equal to the thickness of the flame-retardant soft ceramic layer.
[0011] As a preferred technical solution, the thickness of the label release paper layer is 0.08 mm, and the thickness of the label release paper layer is less than or equal to the thickness of the laser engraving printing layer.
[0012] As a preferred technical solution, the thickness of the flame-retardant flexible ceramic layer is greater than or equal to the thickness of the shielding aluminum foil layer, and the thickness of the label adhesive layer is less than or equal to the sum of the thicknesses of the shielding aluminum foil layer and the flame-retardant flexible ceramic layer.
[0013] As a preferred technical solution, the thickness of the laser-engraved printing layer is less than or equal to the sum of the thicknesses of the label substrate layer and the label release paper layer, and greater than or equal to the sum of the thicknesses of the label adhesive layer and the label release paper layer.
[0014] As a preferred technical solution, the thickness of the shielding aluminum foil layer on both sides of the label substrate layer is the same, the thickness of the flame-retardant soft ceramic layer on both sides is the same, and the sum of the thicknesses of the shielding aluminum foil layer and the flame-retardant soft ceramic layer is less than or equal to the thickness of the label substrate layer.
[0015] This utility model provides a novel laser-engraved, high-adhesion, weather-resistant label with the following advantages:
[0016] This invention uses polyester or polyimide film, which has excellent weather resistance and mechanical strength, as the label substrate. By bonding a printing layer and an adhesive layer to the substrate, laser engraving printing technology enables high-precision printing of patterns and text on the label surface. The printing effect is durable and clear, suitable for printing complex patterns and barcodes. The high-performance acrylic resin adhesive gives the label high initial tack and adhesion, allowing it to adhere firmly to various material surfaces and maintain stable adhesion under different environmental conditions. The use of weather-resistant substrate and UV-resistant coating allows the label to be used for a long time in harsh outdoor environments, resisting the erosion of ultraviolet rays, rain, high and low temperatures, maintaining the functionality and aesthetics of the label. Laser engraving printing technology eliminates the need for ink, reducing environmental pollution and improving printing efficiency, making it suitable for large-scale production.

[0022] like Figure 1 As shown, a novel laser-engraved high-adhesion weather-resistant label includes a label substrate layer 1 disposed in the middle, a laser-engraved printing layer 2 disposed on the upper layer of the label substrate layer 1, a label adhesive layer 5 disposed on the lower layer of the label substrate layer 1, and a label release paper layer 6 disposed on the lower layer of the label adhesive layer 5; shielding aluminum foil layers 3 are wrapped on both sides of the label substrate layer 1, a flame-retardant soft ceramic layer 4 is disposed between the shielding aluminum foil layer 3 and the laser-engraved printing layer 2, and a flame-retardant soft ceramic layer 4 is also disposed between the shielding aluminum foil layer 3 and the label adhesive layer 5.
[0023] Furthermore, the thickness of the label substrate layer 1 is 0.075 mm, and the thickness of the label substrate layer 1 is less than or equal to the thickness of the laser engraving printing layer 2.
[0024] Furthermore, the thickness of the label adhesive layer 5 is 0.03 mm, and the thickness of the label adhesive layer 5 is greater than or equal to the thickness of the flame-retardant soft ceramic layer 4.
[0025] Furthermore, the thickness of the label release paper layer 6 is 0.08 mm, and the thickness of the label release paper layer 6 is less than or equal to the thickness of the laser engraving printing layer 2.
[0026] Furthermore, the thickness of the flame-retardant flexible ceramic layer 4 is greater than or equal to the thickness of the shielding aluminum foil layer 3, and the thickness of the label adhesive layer 5 is less than or equal to the sum of the thicknesses of the shielding aluminum foil layer 3 and the flame-retardant flexible ceramic layer 4.
[0027] Furthermore, the thickness of the laser-engraved printing layer 2 is less than or equal to the sum of the thicknesses of the label substrate layer 1 and the label release paper layer 6, and greater than or equal to the sum of the thicknesses of the label adhesive layer 5 and the label release paper layer 6.
[0028] Furthermore, the shielding aluminum foil layers 3 on both sides of the label substrate layer 1 have the same thickness, and the flame-retardant soft ceramic layers 4 on both sides have the same thickness. The sum of the thicknesses of the shielding aluminum foil layers 3 and the flame-retardant soft ceramic layers 4 is less than or equal to the thickness of the label substrate layer 1.
[0029] First, the substrate layer and the printing layer are laminated using a hot-pressing process. Then, a layer of high-performance acrylic resin adhesive is coated on the back of the substrate layer. Finally, a release paper layer is covered to form the final laser-engraved, high-adhesion, weather-resistant label material. The label material is tested for printing accuracy, adhesion, weather resistance, and durability. The label material maintains stable performance in harsh outdoor environments, with clear and durable printing results.

The shielding aluminum foil layer 3 can improve the ductility of the material, and the flame-retardant soft ceramic layer 4 can improve the high temperature resistance and flame retardancy of the label material. Example 2
[0031] The difference between this embodiment and Embodiment 1 is that:
[0032] like Figure 1 As shown, a novel laser-engraved high-adhesion weather-resistant label consists of only a label substrate layer 1, a laser-engraved printing layer 2, a label adhesive layer 5, and a label release paper layer 6. The label substrate layer 1 contains metal fibers, fiberglass aerogel, and ceramic fibers, which significantly improves the label's high-temperature resistance, weather resistance, and flame retardancy.
[0033] In this invention, the label uses a polyester film or polyimide film with excellent weather resistance and mechanical strength as the label substrate. By bonding a printing layer and an adhesive layer to the substrate, laser engraving printing technology enables high-precision printing of patterns and text on the label surface. The printing effect is durable and clear, suitable for printing complex patterns and barcodes. The high-performance acrylic resin adhesive gives the label high initial tack and adhesion, allowing it to adhere firmly to the surface of various materials and maintain stable adhesion under different environmental conditions. The use of a weather-resistant substrate and a UV-resistant coating allows the label to be used for a long time in harsh outdoor environments, resisting the erosion of ultraviolet rays, rain, high and low temperatures, maintaining the functionality and aesthetics of the label. Laser engraving printing technology eliminates the need for ink, reducing environmental pollution and improving printing efficiency, making it suitable for large-scale production.
